The AIE Vertical Automatic Constant Heat Sealers are designed for applications that require vertical sealing such as the packaging of powders and liquids as well as very heavy bags that are difficult to lift. They can be combined with a conveyor for filling, and they come with an extra long stand for added flexibility. With these machines, you can seal materials up to 20 mil thick (combined thickness up to 40 mil). The height from floor to sealing jaws is 42". They come with an electric foot pedal controlled but they can also be operated automatically.
